Space enthusiasts debate modifying Mars for man
Khaleej Times

Space enthusiasts are conducting a lively debate about whether to make the planet Mars habitable for human beings, or to leave it in its pristine state as a place hostile to life. Technology offers various ways to provide Mars with an Earth-style atmosphere and gradually warm it up over several centuries. The prospect recalls warnings from cosmologist and physicist Stephen Hawking that continued climate change on Earth may one day leave humanity no other choice but to emigrate to another world.
